摘要

提出了一种分段磁体无槽永磁电机的解析模型。永磁体建模采用安培法,电机各磁气隙磁场采用分离变量法。该模型通过在磁体区域内引入体积电流密度以及磁体区域边界上的表面电流来考虑平行磁化磁体段。用有限元包对模型进行了验证。

Analytical model of parallel magnetized magnet segments of surface PM slotless machine
An analytical model of slotless PM motor with segmented magnets is presented. The Ampere's approach is adopted for the modeling of permanent magnets and separation variables method is used to calculate magnetic field in all magnetic air-gap of the motor. The model considers parallel magnetized magnet segments by the introduction of volume current densities inside the magnet regions as well as surface currents on their boundaries. A finite element package is used to validate the proposed model.
